[Dnsmasq-discuss] Announcing 2.20

[Simon Kelley]

Dnsmasq version 2.20 is now available: CHANGELOG entry looks like this:

             Allow more than one instance of dnsmasq to run on a
             machine, each providing DHCP service on a different
             interface, provided that --bind-interfaces is set. This
             configuration used to work, but regressed in version 2.14

             Fix compilation on Mac OS X. Thanks to Kevin Bullock.

             Protect against overlong names and overlong
             labels in configuration and from DHCP.

             Fix interesting corner case in CNAME handling. This occurs
             when a CNAME has a target which "shadowed" by a name in
             /etc/hosts or from DHCP. Resolving the CNAME would sneak
             the upstream value of the CNAME's target into the cache,
             alongside the local value. Now that doesn't happen, though
             resolving the CNAME still gives the unshadowed value. This
             is arguably wrong but rather difficult to fix. The main
             thing is to avoid getting strange results for the target
             due to the cache pollution when resolving the
             CNAME. Thanks to Pierre Habouzit for exploring the corner
             and submitting a very clear bug report.

             Fix subtle bug in the DNS packet parsing code. It's almost
             impossible to describe this succinctly, but the one known
             manifestation is the inability to cache the A record for
             www.apple.com. Thanks to Bob Alexander for spotting that.

             Support SRV records. Thanks to Robert Kean for the patches
             for this.

             Fixed sign confusion in the vendor-id matching code which
             could cause crashes sometimes. (Credit to Mark Wiater for
             help finding this.)

             Added the ability to match the netid tag in a
             dhcp-range. Combined with the ability to have multiple
             ranges in a single subnet, this provides a means to
             segregate hosts on different address ranges based on
             vendorclass or userclass. Thanks to Mark Wiater for
             prompting this enhancement.

             Added preference values for MX records.

             Added the --localise-queries option.


Cheers,

Simon.
